check engine light, poor running, odbII code V70-XC70 2007

posted by  someone claiming to be Bob on  Sun Nov 20 07:13 CST 2016 [RELATED]

Last weekend my check engine light went on in the early morning, ran around to most of the parts stores to find out that they will no longer to code readings on vehicles.

Was able to get a local garage to get me a code. P0101

Mass Air Flow

Engine compartment is extremely clean, no issues with wires, everything still in the same place when bought new as far as the harness goes.

Opened the air box, took out the air filter and dropped it on the side walk, one big cloud of dirt. Got a replacement filter. Went back home and took the air box apart, vacuumed it out, took the mass air flow unit off the box and cleaned that with Mass Air Flow cleaner by CRC. Put everything back together and then after a day of driving the check engine light went out and everything was okay.

Then last night the check engine light came back on.

Need to get the code read again.

What do you think could be the issue now?
Could it be the MAF unit?

Let me know. Thanks.
